Self-pay vs health insurance: how do the costs compare?

More patients are paying for private hospital treatment themselves, even though insurance still covers the majority of admissions.

Self-funded admissions rose 7.7% to a record high in the first quarter of 2026, according to the Private Healthcare Information Network (PHIN), while insurance-funded admissions fell 2.6%.

Of private hospital admissions, 31% were self-funded, compared with 69% paid for through insurance.

Paying for treatment yourself means avoiding regular insurance premiums, but a single operation could cost thousands of pounds. We compare self-pay with private medical insurance and explain the costs and risks to consider.

How much does private treatment cost?

Costs vary depending on the treatment, provider, location and care you need. 

An initial appointment with a private consultant typically costs £150 to £300, according to the PHIN, while surgery can run into thousands of pounds. 

Here are some prices currently published by private healthcare providers: 

Some providers offer packages covering the main treatment costs, but consultations, tests, medication, extra hospital stays and aftercare may cost more. Where there's no package, you could receive separate bills from the hospital, consultant and anaesthetist. 

Before committing, ask for a written quote setting out what is included, what you’ll pay separately and how the bill could change if you need additional care.

Self pay vs health insurance 

Self-pay may make sense if you need a particular, affordable treatment and have enough savings to cover the full bill. Private medical insurance may offer more reassurance if an unexpected private treatment bill would be difficult to absorb, although it won’t cover every condition or procedure. 

One important distinction is that private medical insurance generally covers eligible treatment for new medical conditions, rather than treatment you already know you need. If you have symptoms or a pre-existing condition, a new policy may not cover the costs.

The cost of cover varies considerably with age and the level of protection chosen. Average sample quotes analysed for Which? by LifeSearch in June 2026 ranged from £32.81 a month (£393.72 a year) for core cover for a 30-year-old, to £280.11 a month (£3,361.32 a year) for comprehensive cover for an 80-year-old. The quotes were for a single non-smoker in an OX postcode, with a standard excess and guided hospital list.  

The premium may not be the end of the bill. You could also have to pay an excess when you claim, or cover a shortfall if your consultant charges more than your insurer will pay.  

The key trade-offs are:

• With self-pay, you only pay when you use private healthcare, but you carry the risk if treatment becomes more complicated or expensive. 
• With health insurance, regular premiums spread the risk of eligible treatment costs, but you’ll pay whether or not you claim. 

The better option depends partly on whether you need a particular treatment now or want protection against potentially expensive treatment in the future.

What won’t private medical insurance cover?

Private medical insurance can provide a useful safety net, but it isn’t an all-access pass to private healthcare. It mainly covers acute conditions, which are illnesses or injuries expected to respond to treatment, and the exact exclusions vary by policy.  

Common gaps and restrictions include: 

• Pre-existing conditions: symptoms, illnesses or treatment from before the policy started may be excluded, depending on how the policy is underwritten. 
• Chronic conditions: routine monitoring and ongoing management of long-term illnesses are generally not covered, although treatment for an acute episode may be. 
• Some treatments and services: cover for outpatient tests, mental health care, physiotherapy and cancer treatment can vary. 
• Certain hospitals or consultants: going outside the insurer’s approved list could leave you paying some or all of the bill.  

If you already have symptoms or know you need treatment, don’t assume that a new policy will pick up the bill. Check the terms and get authorisation from your insurer before arranging care, including confirmation of which hospitals and consultants you can use.  

5 ways to keep private healthcare costs down

Private care can be expensive, but the first price you see doesn’t have to be the final word. 

1. Shop around: if you’re self-paying, compare prices from several hospitals and consultants. For insurance, compare excesses, exclusions and treatment limits as well as the monthly premium. 
2. Don’t overlook workplace cover: Only 18% of employees whose company offers benefits are fully aware of everything available to them. Your employer may provide private medical insurance or let you join a workplace scheme, potentially reducing how much you need to pay yourself. 
3. Trim your policy carefully: choosing a higher excess, shorter hospital list or reduced outpatient cover could lower your premium. Just make sure the savings are worth any extra costs or travel you could face when claiming.  
4. Mix private and NHS care: you could pay privately for a consultation or diagnosis, then ask whether your treatment is available through the NHS. However, you may need another assessment and will join the relevant waiting list, rather than receiving priority because you paid privately.  
5. Give your policy an annual check-up: at renewal, check whether the premium, excess and cover still meet your needs. Resist cutting useful benefits simply to bring down the price. 

The cheapest route won’t always offer the best value. Shaving money off your premium now could leave you facing a larger bill when you need treatment.
